Re: [R] Double / single backticks for inline R code in an Rmarkdown file

[Yihui Xie]

params$data is "hawaii" in this case, so the output of

  ``r params$data``

is

  `hawaii`

The double backticks don't have any special meaning here. Only the
inside pair of backticks (i.e. `r `) makes sense to R Markdown (or
precisely speaking, knitr). The outside pair will be left untouched
after knitr evaluates the inline R expression `r params$data`. After
evaluation, there won't be double backticks. This has nothing to do
with the left curly double quote LaTeX. The result `hawaii` will be
converted to hawaii if the output format is HTML (or
\texttt{hawaii} if the output format is LaTeX), but the extra
backticks in the original Rmd document is completely optional. It all
depends on whether you want to place the result in a code tag or
command.

Regards,
Yihui

Re: [R] Double / single backticks for inline R code in an Rmarkdown file

[Jeff Newmiller]

No, you don't misunderstand. But you might want to be aware that targeting PDF 
output uses LaTeX which regards double backticks as a method of encoding a left 
curly double quote mark, so this error could derive from an incomplete 
adaptation of the Rmd file for HTML output even though such a symbol doesn't 
make sense there in PDF either.

Re: [R] Installing dyplr on Linux requires a ton of chasing down dependencies

[Collin Lynch]

Adam, while I am not familiar with that particular variant of linux,
it sounds like a package manager mismatch in that the ubuntu package
looks for specific libraries which are named differently on your
system.  If you can run a GUI then you have some form of X but the
libraries may be named differently.  It looks like Pop uses apt so you
might try apt-get for R and see if that works or consider compiling
from source.

[R] Double / single backticks for inline R code in an Rmarkdown file

[Ashim Kapoor]

Dear All,

I am reading this file :-

https://rmarkdown.rstudio.com/lesson-6.html

My query is : In line 14 of the above file, ie.

The [marmap](https://cran.r-project.org/web/packages/marmap/index.html)
package provides tools and data for visualizing the ocean floor. Here is an
example contour plot of marmap's ``r params$data`` dataset.

Should not the phrase rparams$data be within SINGLE backticks ?

Do I misunderstand?

Thank you,
Ashim

Re: [R] Installing dyplr on Linux requires a ton of chasing down dependencies

[Dirk Eddelbuettel]

Adam,

You may find this blog post and the video instructive:

  http://dirk.eddelbuettel.com/blog/2019/06/09#022_rocker_and_ppas

It illustrates how 'installing tidyverse' (or rstan) can be a single and done
in under two minutes == on Linux, with the appropriate distribution and
settings.  In short:  some have binaries prebuilt, some don't.

My blog has a few post in the 'r4' section on that as well as on other
approaches to this.

  http://dirk.eddelbuettel.com/blog/code/r4/

Now, you choose a somewhat non-standard distro. The price of that choice may
indeed be that you have to install everything (R/CRAN-related) from source. 

Hope this helps, Dirk

Re: [R] Installing dyplr on Linux requires a ton of chasing down dependencies

[David Winsemius]

Generally problems involving Ubuntu are sent to r-sig-Debian but maybe your new 
OS is not in that heritage. If not, you may get a more informed audience at 
r-devel. (Technically this is more on-topic there than on rhelp.) But you 
should read the Posting Guide, subscribe, post in plain text, and include more 
of the text from the errors.

Re: [R] Installing dyplr on Linux requires a ton of chasing down dependencies

[WU Degang]

Sorry to digress here. Having used CRAN and conda to manage R packages, I find 
that using conda to install R packages will cause more troubles than CRAN. I 
would stick with CRAN.

I just got a new Linux computer running Pop!_OS.  If I download R from the

I tried installing Anaconda and doing everything within there.  It delivers
